TURBINE.

Specification of Letters Patent.

Patented June 30. 1914.

Application filed December 10, 1913. Serial No. 805,718.

lie it known that. 1, CHARLES W. DARE, a citizen of the United States, residing at (hit-ago, in the county of Cook and State of r Illinois, have. invented a certain new and useful Improvement in Turbines, of which the following is a specification.

i\l v invention relates to steam turbines and is illusratcd diagrammatically in the accompanying drawings, wherein-- Figure l is a side elevation with parts broken away and parts in section; Fig. 21s a section along the line 2- of Fig. 1.

Like parts are indicated by the same letter in both figures.

A is a turbine housing having the steam chest A and exhaust iipe A and containing a rotor A provided with buckets A an :zrsted on a shaft A".

A is a drip or drainage pipe discharging from the bottom of the housing A to take care of condensation and the 1i (0.

B is a substantially conical closure or cap which forms one side of the housing A and is held in position by the cap screws B. It contains adjacent its outer smaller end the oil chamber B, which chamber is hounded on the inner side by a partition wall B. This wall B, together with the main end wall of the cap, is provided with a circular entral aperture in which is slidablv mounted a hearing sleeve B to engage an support the end of the shaft A". The outer end of this sleeve and of the shaftis covered by an integral cap B carried by the cap The sleeve B is provided with the slot. C to permit the oiling ring C to ride upon the shaft A and rotate with it, whereby asthe shaft rotates oil may be picked up by the ring from the oil reservoir and carried to the top of the shaft to lubricate the shaft. A vane or flange C projects inwardly from the wall of the cap B above the bearing sleeve B and overlies the slot C to prevent, when the arts are in the workin position shown in ig. 1, any accidental disarrangement of the oiling ring from the slot such as might take place owing to joltlng or other movement of the apparatus.

D is an assembly slot or aperture in the wall B through which the oiling ring 0 may be introduced into the chamber B. It is loosely closed by thecap or shutter D.

D is a spillway or overflow channel mounted on the wall 13 communicating at its 7 many changes might be made in form, size,

shape and arrangement of parts without departing materially from the spirit of my iii-- vention. I wish, therefore, that mydrawing be considered as in a sense diagrammatic.

The use and operation of my invention are as follows: Mv device is assembled by first introducing the oiling ring throng the assembly slot into the oil chamber. The

bearing sleeve is then slowly forced into position in suchwise that it passes through the oiling ringand in suchwise that the oiling ring rests in the slot therein. The sleeve is then'fmeed into the position shown in Fig. 1, whereupon the oiling ring is held loosely in the slot by the flange or vane above it. The rotor and shaft are then placed in the housing in the usual way, the shaft being supported at the other end by a bearin not shown and the conical head or wall is p aced in position in such manner that the end of the shaft passes through the bearing sleeve and supports the oiling ring. The whole device is then tightened up and ready for use. Before the engine is started, of course, oil or grease or some fluid lubricant is introduced into the oil chamber and when steam is turned on to rotate the rotor, the shaft rotates, carryin the oiling ring, which in turn carries up tfie lubricant from the chamber to feed it to the shaft. .It will be noted that no effort is, made to pack the end of the shaft or otherwise prevent the discharge of air, steam or water of condense-- tion from the turbine chamber into the oil chamber, though its egress from this chamber is rcvented by means of a cap or grease cup. 5 he result of this will be that the pressure in the two chambers will be the same and a certain amount of steam and water of condensation will find its way into the oil chamber. This water being, of course of greatr, specific gravitv than the oil will sink to the bottom of the chamber, and as the quantity increases it will be drawn 01! through the overflow when the level of liquid in the chamber reaches a int. higher than the level of the overflow, ut owing to the fact that the water seeks the bottom of the chamber, it will be water which is discharged and notoil, and no harm will be done b this water, since it will be 'free to run 0 through the drip pipe as shown at the bottom 0 the turbine housing. When it is desired to lay the machine up out of ing sleeve slidabl sup orted in an extend-- ing through sai poc et, an oil ring contamed within saidjpocket and surrounding said bearing sleeve, said bearing sleeve being slotted, a. shaft within said, sleeve upon which the oiling ring rests-es it liesin the slot in the sleeve and a flange overlying said slot to hold said ring in position.

3. In a turbine an oiling, ket, a hearing sleeve slidabl sup orted in and extending throu h sai poo at, an oil ring contamed wit in said pocket and surrounding said bearing sleeve, said bearing sleeve bein slotted, a shaft'within said sleeve upon w ich-the oiling ring rests as it lies in the slot in the sleeve and a flange overlying said slot to hold said ringin position, an assem-' bly pocket in the wall of said pocket to permit introduction of the oiling ring and a cover therefor.

4. In a turbine, a two-part housing, one

ing it removably to the remainder of" the housing, an Oil 'pocket, centrally located within said conical cap and a bearing sleeve carried in said oil pocket, means located within said cil pocket carried by said sleeve for conveying oil from the bottom of the pocket to said bearing.

6. In a turbine, a two-part housing, one

part of said housinf; taking the form of a substantially conica cap, means for attaching it removubly to the remainder of the housing, an oil lpocket centrally located within said conica cap and a bearing sleeve carried in said oil pocket, means located within said oil pocket, 'carried by said sleeve for conveying oil from the bottom of the pocket to said bearing, sa1d pock et being in communication with the lnterior of the housing and an overflow communicating with the bottom of said pocket and discharging into. saidhousing at the normal li uid level of said pocket.

' The combination with a bearing of an oil pocket surrounding it, means for lllblleating said bearing from 881d Oll pocket and anoverfiow from said pocket communicating'with the bottom thereof and discharging at the normal liquid level thereof.

In'te'stimon whereof, I afi'ur my signature in thepresence of two witnesses this 8th day of December 1913.
